Objective: This study aims to analyze saliva composition in crack users using vibrational spectroscopy.
Material And Methods: A total of 90 participants were meticulously selected and divided into three groups, each comprising 30 individuals. All participants met the criterion of having no observable clinical changes in the oral mucosa. The groups included active crack users with a minimum usage duration of 30 days, ex-crack users, and non-crack users. Rigorous inclusion and exclusion criteria were applied during participant selection to ensure the study's precision. Saliva analysis was performed using vibrational spectroscopy with FTIR (Fourier-transform Infrared spectroscopy).
Results: Pre-processed spectra enabled statistical comparability. Salivary biomarkers revealed clinical implications, including findings related to xerostomia, caries, and periodontal or systemic conditions such as lung cancer.
Conclusion: The research uncovers significant compositional differences in the saliva of current users, former users, and non-users of crack. This nuanced understanding contributes to the discourse on substance abuse, highlighting the potential of saliva analysis for discerning different stages of crack use. The investigation suggests options for further exploration in clinical and forensic contexts, promising advancements in addiction research and diagnostics.

In the current research mushroom/bentonite clay (RDBNC) as a low-cost bionanosorbent was investigated for adsorption of methylene blue (MB) and malachite green (MG) dye from contaminated water. The bionanosorbent was characterized by Fourier transform infrared (FTIR), X-ray diffraction (XRD), Scanning electron microscopy (FESEM), Thermal Gravimetric Analysis (TGA), and Zeta-potential techniques. Adsorption experiments of RDBNC for MB, MG dyes following Freundlich isotherm and pseudo second order kinetic models.

This work reports the synthesis of a copper metal complex with the nonsteroidal anti-inflammatory drug (NSAID) ibuprofen, and 2,2'-dipyridylamine employing microwave-assisted synthesis (MWAS). To the best of authors knowledge, this is the first study reporting a NSAID-based complex achieved through MWAS. The coordination compound was characterised by elemental analysis, Fourier transform infrared spectroscopy, thermogravimetry, and ultraviolet-visible spectrophotometry.

Biphasic calcium phosphate (BCP) is a bioceramic widely used in hard tissue engineering for bone replacement. BCP consists of β-tricalcium phosphate (β-TCP) - a highly soluble and resorbable phase - and hydroxyapatite (HA) - a highly stable phase, creating a balance between solubility and resorption, optimally supporting cell interactions and tissue growth. The β-TCP/HA ratio significantly affects the resorption, solubility, and cellular response, with a higher β-TCP ratio increasing resorption due to its solubility.
